I recently bought a knife off of ebay. It was listed as 25OT but when it arrive the tang was stamped "Schrade" over "USA 225OT" It looks very similar to the 25OT except it doesn't have a lanyard hole. The main blade also has the thumb pick located right at the angle change on the back of the blade (rather than further up toward the point like the 25OT). The second blade is not a saw like a typical 225OT but your standard skinner just like the 25OT. Also, neither blades have press lock like the true 225OT. What is this thing? Is it a fake or something that was only in production for a short time?
